Abstract

A photonic crystal fiber (PCF) made of the cyclic-olefin copolymer (COC) with low dispersion and confinement loss, large-mode-area, and single-mode transmission for terahertz wave guiding is described. The characteristics of the PCF in the terahertz range are simulated and analyzed by the full-vector finite element method (FEM). The effects of the structural parameters on the performance of the terahertz PCF are also investigated. The effective mode field area of the PCF is as large as 1.22084 × 107 μm2 at a wavelength of 1,000 μm and a flat dispersion of 0.07669 ± 0.33258 ps/nm/km is obtained. A much lower confinement loss of 6.0253 × 10-16 dB/m is achieved. The single mode transmission over the entire terahertz wave band is described.
